Calle 13 has released a video teasing a song created in collaboration
with WikiLeaks’ founder Julian Assange using messages from fans’ Tweets
and featuring Rage Against the Machine guitarist Tom Morello and
Palestinian vocalist and musician Kamilya Jubran.

“We’re going to take their voice, what they’re saying, their idea,
and we’re going to manipulate their idea and construct a song about the
media,” Calle 13's Rene Pérez tells Assange, referring to Twitter
followers. The track’s “trailer” has a covert, thriller movie vibe, with
the pair huddling over MacBook Pros, and includes some hardcore rapping
from Pérez. “To talk against the bad media but using their voices.”

Pérez, frontman of the Puerto Rican duo, visited Assange in the
Ecuadorian Embassy in London last June. Using the hashtag
#JulianAssangeCalle13, they sent out questions on various themes of
social justice and received thousands of responses.

The track, called “Multi_Viral” is the first from Calle 13’s upcoming
album, which they plan to release independently after a split with Sony
Music Latin. The band announced today via the video that they will
debut the complete single on Nov. 13.

Calle 13’s Eduardo Cabra told Billboard last week the single would be
released Nov. 12, although he mentioned that the now-confirmed release
date was a logical option: “13 for Calle 13.” Cabra said the album is
planned for release in March.

“We’re looking at different platforms,” Cabra said. “Maybe we will give it away for free.”
